Implementations§

source§

impl<'a, Id> NamedReference<'a, Id>where Id: for<'k> Key<'k>,

source

pub fn into_owned(self) -> NamedReference<'static, Id>

Converts this reference to an owned reference with a 'static lifetime.

source

pub fn id<Col, Cn>( &self, connection: &Cn ) -> Result<Option<<Col as Collection>::PrimaryKey>, Error>where Col: NamedCollection<PrimaryKey = Id>, Cn: Connection,

Returns this reference’s id. If the reference is a name, the NamedCollection::ByNameView is queried for the id.

source

pub async fn id_async<Col, Cn>( &self, connection: &Cn ) -> Result<Option<<Col as Collection>::PrimaryKey>, Error>where Col: NamedCollection<PrimaryKey = Id>, Cn: AsyncConnection,

Returns this reference’s id. If the reference is a name, the NamedCollection::ByNameView is queried for the id.
